TechNiche International gets 'HyperKewl' with vests

TechNiche International's HyperKewl vests are evaporative cooling sport vests that are made of polymer-embedded fabric, which activates when the user submerges the garment in water.

When worn, the water in the fabric evaporates, which helps cool the body in the same way we do when we sweat, the company says. Users will feel 15 to 20 degrees cooler than without the vest, for about two to five hours.

The HyperKewl fabric also will be featured in cooling beanies, skull caps and neck coolers.
